Technical Field

Background

At present, the existing dual-light fusion device is generally composed of two independent camera modules, wherein the two camera modules comprise a common RGB camera and an infrared camera module. The two camera modules respectively shoot and then output images to an image processing chip, and the image processing chip analyzes the images and then fuses the images through an algorithm to obtain a double-light fusion image. However, after the two camera modules output images, the target image can be obtained only after the image processing chip is used for resolving and fusing, and the imaging time is long, so that a certain delay exists between actual picture display and shooting. Two camera modules generally need to be matched with two different image sensors, so that the cost of the double-light fusion device is high, and in addition, extra calibration is needed in the production process, so that the precision requirement on the production device is extremely high. Meanwhile, the resolution of the infrared camera is generally smaller than that of the RGB camera, and the loss of pixels at the edges of the image can be caused after algorithm fusion, so that the resolution of the target image is lower than that of the infrared camera, and the image quality is low.

Referring to fig. 1 in combination, an internal structure of a dual-light fusion imaging device according to an embodiment of the utility model is shown. The dual-light fusion imaging device 1 is applied to electronic equipment with a camera shooting function, wherein the electronic equipment comprises, but is not limited to, a smart phone, a tablet computer, a notebook computer, a smart watch or a smart door lock.

The dual light fusion imaging apparatus 1 includes a filter assembly 10, a rotation assembly 13, and an imaging assembly 30. Specifically, imaging assembly 30 includes a camera 20, and camera 20 includes a lens 21. In the present embodiment, the camera 20 includes at least two lenses 21. The thickness, curvature, optical parameters, and the number of the lenses 21 and the gaps between the lenses 21 can be set according to the actual requirements, and are not limited herein.

The initial light passes through the filter assembly 10 to form a first incident light or a second incident light, the wavelength of the first incident light and the wavelength of the second incident light being different. In this embodiment, one of the first incident light and the second incident light is visible light, and the other is infrared light. That is, the first incident light is visible light and the second incident light is infrared light, or the first incident light is infrared light and the second incident light is visible light. Hereinafter, the first incident light is visible light and the second incident light is infrared light will be described in detail.

The filter assembly 10 includes a first filter 11 and a second filter 12. Specifically, the initial light passes through the first filter 11 to form a first incident light, and the initial light passes through the second filter 12 to form a second incident light. It is understood that the first filter 11 can transmit light having a wavelength of 380-780nm, i.e., visible light; the second filter 12 is capable of transmitting light of 930-950nm wavelength, i.e. infrared light. The initial light is natural light, only visible light is reserved after the initial light passes through the first optical filter 11, and only infrared light is reserved after the initial light passes through the second optical filter 12.

The rotation assembly 13 is configured to alternately make the first incident light and the second incident light incident to the imaging assembly 30, and the imaging assembly 30 exposes only the first incident light or the second incident light at a time to obtain a target image. It will be appreciated that when the rotation assembly 13 is incident the first incident light to the lens 21, the imaging assembly 30 exposes the first incident light; when the rotation assembly 13 makes the second incident light incident to the lens 21, the imaging assembly 30 exposes the second incident light.

When the imaging component 30 exposes the first incident light, the rotation component 13 makes the first incident light incident on the lens 21 and blocks the second incident light incident on the lens 21; alternatively, the rotation assembly 13 passes the initial light through the first filter 11 and blocks the initial light from passing through the second filter 12. It will be appreciated that when the rotation assembly 13 passes the initial light through the first filter 11 and blocks the initial light from passing through the second filter 12, the initial light forms only the first incident light. Therefore, when the imaging device 30 exposes the first incident light, only the first incident light is incident on the lens 21.

When the imaging component 30 exposes the second incident light, the rotation component 13 makes the second incident light incident on the lens 21 and blocks the first incident light from incident on the lens 21; alternatively, the rotation assembly 13 passes the initial light through the second filter 12 and blocks the initial light from passing through the first filter 11. It will be appreciated that when the rotation assembly 13 passes the initial light through the second filter 12 and blocks the initial light from passing through the first filter 11, the initial light forms only the second incident light. Therefore, when the imaging device 30 exposes the second incident light, only the second incident light is incident on the lens 21.

The rotation assembly 13 includes a rotation member 131, a light-transmitting member 132, and a rotation motor 133. In this embodiment, the rotating member 131 is disposed on the rotating motor 133, and the rotating motor 133 can drive the rotating member 131 to rotate. The light-transmitting member 132 is disposed on the rotating member 131 and is rotatable around the rotating member 131. Specifically, one end of the rotary member 131 is fixed to the rotary motor 133, and the other end is provided with the light-transmitting member 132. When the rotary motor 133 drives the rotary member 131 to rotate, the rotary member 131 drives the light-transmitting member 132 to rotate together. The rotation motor 133 is two high-speed motors.

In the present embodiment, the light-transmitting member 132 includes a light-shielding portion 1321 and a light-transmitting portion 1322. The light can pass through the light-transmitting portion 1322, but cannot pass through the light-shielding portion 1321. Preferably, the light-transmitting member 132 is in an axisymmetric pattern, and the light-shielding portion 1321 and the light-transmitting portion 1322 are symmetric about the symmetry axis of the light-transmitting member 132. The light-transmitting member 132 is a black-and-white color wheel, in which half of the white color is a light-transmitting portion 1322 and half of the black color is a light-shielding portion 1321. Specifically, the center of the light-transmitting member 132 is fixed to the rotating member 131, and the first filter 11 and the second filter 12 are symmetrically disposed with respect to the rotating member 131.

When the light-transmitting member 132 rotates until the light-transmitting portion 1322 faces the first filter 11 and the light-shielding portion 1321 faces the second filter 12, only the first incident light is incident on the lens 21. When the light-transmitting member 132 rotates until the light-transmitting portion 1322 faces the second filter 12 and the light-shielding portion 1321 faces the first filter 11, only the second incident light enters the lens 21. In the present embodiment, the size of the light-transmitting member 132 is adapted to the positions and sizes of the first and second filters 11 and 12. Regardless of the positions and sizes of the first filter 11 and the second filter 12, when the light-transmitting portion 1322 is aligned with the first filter 11 or the second filter 12, the projection of the first filter 11 or the second filter 12 is to fall entirely within the range of the light-transmitting portion 1322; when the light shielding portion 1321 is aligned with the first filter 11 or the second filter 12, the projection of the first filter 11 or the second filter 12 is to fall entirely within the range of the light shielding portion 1321.

In the present embodiment, after the first incident light is incident on the lens 21, the light-transmitting member 132 rotates 180 ° to make the second incident light incident on the lens 21. Then, the light transmitting member 132 is rotated again by 180 ° so that the first incident light is incident on the lens 21, thereby circulating. Meanwhile, when only the first incident light is incident to the lens 21, the imaging assembly 30 exposes the first incident light; when only the second incident light is incident on the lens 21, the imaging device 30 exposes the second incident light. It will be appreciated that during rotation of the transparent member 132, the first incident light and the second incident light may be incident on the lens 21 at the same time, and the imaging assembly 30 does not perform exposure.
